What Trelegy Ellipta is used for
Trelegy Ellipta is a once-daily inhaler combining three medicines: an inhaled corticosteroid (fluticasone furoate), a long-acting anticholinergic (umeclidinium) and a long-acting bronchodilator (vilanterol). Its FDA label covers maintenance treatment of COPD and of asthma in adults. It isn't a rescue inhaler.
This page explains Medicare coverage only. Questions about whether Trelegy Ellipta is right for you belong with your prescriber.
Which part of Medicare covers Trelegy Ellipta
Trelegy Ellipta is a handheld dry-powder inhaler, so it's a Part D drug. Plans may ask your prescriber to show that you've tried a one- or two-medicine inhaler first (step therapy) before covering a three-in-one inhaler.
Is Trelegy Ellipta on Medicare's negotiated-price list?
CMS selected Trelegy Ellipta in the second round of the Medicare Drug Price Negotiation Program. CMS says its negotiated price takes effect January 1, 2027. A negotiated price is what Medicare drug plans and pharmacies pay; it isn't your copay. What you pay still depends on your plan's cost sharing. Two related Ellipta inhalers are also on CMS's lists: Breo Ellipta was selected in the same second round (negotiated price effective January 1, 2027), and Anoro Ellipta was selected in January 2026 for the third round, with prices taking effect in 2028.
Comparing plans for Trelegy for 2027
Open Enrollment ends December 7, 2026. Because the negotiated price starts January 1, 2027, plans had it in view when they built their 2027 formularies, but they still decide whether to cover Trelegy, on what tier and with what rules. Look up Trelegy Ellipta, plus your rescue inhaler, on each plan you're considering. If you're switching from Trelegy to separate inhalers or the other way around, check every product involved.
What you pay for Trelegy Ellipta in 2027: the out-of-pocket cap
Your cost for Trelegy Ellipta depends on your plan: its deductible, the tier it puts the drug on, and whether you use a preferred pharmacy. This site doesn't list plan costs; your plan's formulary and Evidence of Coverage do. What Medicare sets for everyone with Part D is the limit:
- 2027 out-of-pocket cap: $2,400 (it was $2,100 in 2026). Once what you pay for covered Part D drugs (deductible, copays and coinsurance) reaches the cap, you pay nothing more for covered Part D drugs for the rest of 2027.
- The maximum Part D deductible for 2027 is $700. No plan can set a higher deductible.
- Only covered drugs count. If your plan doesn't cover Trelegy Ellipta and you pay cash, or you use a discount card instead of your plan, that spending doesn't count toward the cap.
Spreading the cost: the Medicare Prescription Payment Plan
The Medicare Prescription Payment Plan lets you pay your Part D drug costs in monthly bills from your plan across the calendar year instead of all at once at the pharmacy. Medicare.gov says there's no cost to participate, but it doesn't lower your drug costs; it only changes when you pay. It helps most when costs are high early in the year. To join, call your plan or use its website. More in What is the Medicare Prescription Payment Plan?
Extra Help with Trelegy Ellipta
Extra Help (the Low-Income Subsidy) is a federal program that lowers Part D premiums, deductibles and copays. For 2027, CMS caps Extra Help copays for covered drugs at $5.80 for a generic and $14.40 for a brand-name drug, and some people with full Medicaid pay less. You get Extra Help automatically if you have OHP (Medicaid), a Medicare Savings Program or SSI; otherwise apply through Social Security at 1-800-772-1213 or ssa.gov/extrahelp. See Extra Help in Oregon.
Getting Trelegy Ellipta covered in Oregon
Oregon and Washington share Part D region 30, so standalone Part D plans are offered region-wide. For 2027, Oregon has 8 standalone Part D plans from 4 companies, plus Medicare Advantage plans with drug coverage in most counties (61 open to everyone statewide). Each plan has its own formulary, so one plan's coverage of Trelegy Ellipta tells you nothing about another's.
Where you live in Oregon changes your choices. CMS data show no Medicare Advantage plan open to everyone in Grant, Harney, Lake, Umatilla or Union counties for 2027 (only employer group plans), and only a special needs plan in Curry County. If you live there, coverage for Trelegy Ellipta usually comes from a standalone Part D plan alongside Original Medicare, unless you have employer or other drug coverage. Check your county's numbers on Oregon counties.
If you have both Medicare and OHP, OHP doesn't pay for drugs that Part D covers. The Oregon Health Authority calls this "OHP with Limited Drug": you need a Part D plan (or a Medicare Advantage plan with drug coverage) for Trelegy Ellipta, and you qualify for Extra Help automatically. See OHP and Medicare.
How to check whether a plan covers Trelegy Ellipta
- Write down the exact drug. Name, strength and how often you take it. A plan can cover one form of Trelegy Ellipta and not another.
- Look it up in each plan's formulary. Enter your drugs and ZIP code on PlanMatch or Medicare.gov's Plan Finder to see which plans list Trelegy Ellipta and any rules.
- Read the rules next to the drug. Prior authorization, step therapy or quantity limits mean your prescriber may need to send the plan information before it pays.
- Check your 2027 notice. Your plan's Annual Notice of Change says whether Trelegy Ellipta stays on the formulary next year. Open Enrollment runs October 15 to December 7, 2026, for coverage starting January 1, 2027.
- Get help if you want it. You can request a call from a licensed insurance agent, who can compare plans from the companies they work with, or call 1-800-MEDICARE (1-800-633-4227, TTY 1-877-486-2048) for information on all of your options.
If your plan doesn't cover Trelegy Ellipta, you or your prescriber can ask for a coverage determination or a formulary exception. Once the plan has your prescriber's supporting statement, it generally must decide within 72 hours, or 24 hours if your prescriber says waiting could seriously harm your health. New members can usually get a one-time transition supply of a drug they were already taking while they ask for an exception or switch. See How do I appeal a Medicare denial in Oregon?
